Baron Fig's 'Lock & Key' Has a Hidden Puzzle Inside

Not only is designer notebook company Baron Fig's new 'Lock & Key' set an attractive way to take old-fashioned, handwritten notes, but the cryptic notebook hides a puzzle in its pages. The notebook itself serves as the lock and the pen the key, and only through a combination of the two can consumers unravel the mysteries inside.

The Lock & Key set plays off its mysterious theme in its design. The notebook features a maze illustration on the cover, and it comes with a fold-out insert that seems to lay out the puzzle of the set. The pen, a smooth brass implement, includes a holder engraved with a codex that unveils the meaning of the runes placed throughout the notebooks pages.

Lock & Key is a special edition set, though the pieces are only aesthetically different from Baron Fig's Confidant Notebook and Squire Rollerball pen.
